If yu want your video game to be noticed, what better way than to hire famous singers to advertise it for you?
The theme song for Dynasty Warriors 7 (top video) has shot up to the top of the Oricon music charts in Japan, selling over 162,000 copies in its first week. The song, entitled "Time", is sung by popular Japanese duo KinKi Kids.
The slightly more bizarre theme song for Sengoku BASARA Chronicle Heroes (bottom video) also debuted at #19, selling 38,496 copies in its first week. It is sung by J-rocker T.M. Revolution.
